The final tally isn’t available yet, but data from previous counts show the largest populations are typically found in downtown San Diego.

Data from the count, known locally as WeAllCount by the San Diego Regional Task Force on the Homeless, is used by the U.S. Department of Housing and Urban Development to help determine funding for communities with homeless programs.

Last year’s count found more than 9,100 homeless people throughout the county, a 5 percent increase from the previous year. More than 60 percent of them were unsheltered.

The most concentrated area in 2017, with about 361 people, was south of Market Street and north of San Diego Bay between Petco Park and Interstate 5.

Areas of Oceanside saw some of the largest increases in homeless people, jumping to 67 homeless people in 2017 from 5 in 2014.Golden Hill’s population increased to 155 from 23 during the same time period. In 2014, Vista had about 50 homeless people. Last year’s count identified more than 200.

All data come from the San Diego Regional Task Force on the Homeless, which organizes the count. Vehicles and hand built structures or tents are multiplied by an occupancy factor so some census tracts have a homeless count that is not a whole number. The WeAllCount covers more than 4,000 square miles, representing nearly 600 census tracts. Some census tracts are not included in the count, as they are considered predominantly rural.
